Hi everyone. I feel a little lost. There is so much info on this site, it gets a little confusing to weed through, sometimes. I know enough about the PMD issues to have a basic understanding of the problems associated with it, but not enough to weed through all the info efficiently. I know this issue comes up a lot, but if you could bare with me to discuss this topic again, I'd appreciate it.
The engine quit on me yesterday. Background info: currently about 120,000 miles, IP (I assume the PMD, as well) was replaced under warranty 5 years ago at 89,000 miles. PMD is currently still on the pump.
Around December, I started having various issues, culminating in the quitting today. Here's the jist of the problems since early Decmember:
-- Occasional "Hiccuping" when warming truck up in the morning... but only when using the "high idle" settings. It seems to be better when the block heater has been used, but not perfect. After the coolant gauge needle starts to climb, it will run fine on high idle.
-- About 10 instances of stalling 15 - 30 seconds after the engine started fine. After, it would start right back up and be fine.
-- 5 instances of initial non-start. Engine would crank, try to fire once for a split second, but then just crank. This reminds of the time my ignition module (passlock?) was flaking out a few years ago. However, 4 times when this happened I would move the gear selector through the gears and back to park - it started fine, then. Once, it wouldn't start until about 15 minutes later (which I think is about the safety time built into the Passlock system).
Now, on to yesterday. The engine started fine after work. I drove about 7 or 8 minutes and started to merge onto a highway. I gave it about 3/4 throttle and the engine fell flat like the someone turned the fuel off. I let off the throttle and the engine stayed running. Tried again - same thing. I kept the throttle under 1/2 and it was fine. Started playing around and found if I pushed the throttle down past 1/2 way and KEPT it down, it would stall. Over the course of about 6 or 7 minutes and about 4 miles, it progressively got worse. Eventually I was on the side of the road, able to start the engine after about 30 seconds of waiting, but not able to start going as it would stall. After another minute or so, it wouldn't even start.
I called AAA and had it towed to a local, reputable shop that knows the 6.5's. Ultimately, they are probably going to do the work (time is not friend right now). But I'm very interested in learning more about this engine and it's idiosyncrasies.
Later last night, I stopped by the shop to put my key in their drop box. The engine started (a little reluctantly), but stalled after 15 seconds. It wouldn't start again.
By the way, after reading Buddy's response in another thread and again in one that Acesneight1 pointed me to, this may be of interest, as well: In October or November, I had an issue where I was losing battery juice big time. Turned out to be a loose alternator wire. BUT, in getting the truck running (after it wouldn't start because of the low juice), I did use a battery charger that had a 50amp "start" option. I think I used that feature a few times (maybe 20 seconds at a time).
Sorry for the long post! If you made it this far, thank you for obliging me!
EDIT: On the side of the road, I started to pull the fuel filter to check that, but I didn't have a spare with me so I stopped. I had pulled the filter enough to see what appeared to be clean diesel come spilling out. If that means anything, anyways. I only had a rag or two, as well.
